One of the friends I spoke of has all Mac gear.
If the Mac gear is not too old (like, over 20 to 30 years), it's highly doubtful the Mac amp was the problem.
In addition to the autoformer (which offers a level of speaker protection, Mac also has the following:
Power Guard that monitors and adjusts the input signal at the speed of light and makes real time adjustments to prevent harsh sounding and potentially speaker (https://www.mcintoshlabs.com/products/speakers) damaging clipping
Sentry Monitorâ„¢ - our fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal

I was not suggesting that the Mac gear was responsible. My point was that even with the Mac gear my friend had two issues that he was not protected from. That is why I thought protection n the speakers themselves may be the way to go.
